Vincenzo Nibali (Astana) rode into Paris on a yellow Specialized S-Works Tarmac to mark the Italian's coronation as the 2014 Tour de France champion.

The 29-year-old, who is only the sixth rider in history to win all three of cycling's Grand Tours, traded in the custom shark-themed Tarmac he rode throughout the Tour (save for the cobbles on stage five, when he swapped to the Roubaix 'Classics' bike) for something more fitting for the procession in to Paris.

As a result, Nibali has had the privilege of riding two custom machines at the Tour but it's nothing new to see one-off designs produced by bike manufacturers in honour of some of cycling's best riders in what is the sport's biggest shop window.

With the curtain about to fall on the 101st edition of the Tour de France, we've taken a look back at some of the best custom bikes to feature in this year's edition of the race.
